Hot take: Luffy is just one Haki powerup from surpassing Roger level

If we talk about Luffy's power the only thing he is lacking compared to someone like Roger is Conqueror's Haki mastery. We have seen last chapter with Gaban that there is a much higher level of Conqueror's Haki that Luffy lacks, that's what Luffy lacks compared to people like Shanks, Roger, Garp or even Gaban.

However if we talk about other Luffy's abilities besifes his Haki Luffy is already on that level. His durability is better than most due to his Nika DF, his endurance is straight up ridiculous, he has amazing speed, strength and overpowered hax abilities. The only thing Luffy is lacking is Haki mastery.

Basically if you give Luffy a Haki powerup where he can do what Gaban did recently then I think that added to his DF should put him above Roger Prime.
